VAPORIZER.

Specification of Letters I Patent.

Patented sept. 17,19o7f Application filed June 21,1906. Serial No. 322,696.,

.with air a certain deiinite proportion of liquid fuel,

which proportion will be maintainedsubstantiallyA constant Whether the demand for the mixture be great or small; that is, assuming the vaporizer is connected to an engine of the internal conibustiontype, the construction is such that the proportion of fuel to air constituting the mixture Will be maintained with Vsubstantial uniformity Whether the engine is running at a high speed or a low speed. Many attempts have been made to accomplish this object, and the same have involved additional air inlets, diaphragms, Wing valves and vari- Vous attachments complicating the vaporizer and' only partially serving to accomplish the object intended. p

Such attachments also require much manual adjustment and constant observation. I

i By my new deviceil have successfully attained the desired object and have produced a simple, low cost .vaporizer which is capable of regulation and yet which automatically maintains a mixture of substantial uniformity.

In the accompanying'drawings I have conventionally illustrated the invention by a longitudinal secl tional view showing certain parts in\elevation.

In the drawings, A-A represent an in-take pipe `for an internal combustion engine.

,` B is a well for containing the liquidl fuel. i

C-C/ are pulleys carrying an endlessband D. The pulley C is housed in the .offset portion forming the well B, While pulley Cis housed in another offset portion BC E is a presser roll which may bear against the band .i and by which the tension thereof may be varied for the purposes of regulation, for as v vill be seen the lower the tension on band D the greater will be the volume of fuel carried thereby. As-the tension is increased the volume offuel lifted is lessened.

E conventionally represents a lever vby which the position of theroll E may be varied either manually or A automaticallyas desired.

G is a belt leading' from alsource of power (indicated by the word Motor to one ofthe belt pulleys.

B2 represents a fuel supply pipe through which liquid.

around the same.

fuel is fed to the Well B. Any suitable means may be employed for maintaining a suitable supply of fuel Within the said Well, and, if desired, means may be employed for holding it at a substantially uniform level.

'A represents a shield for .closing off the well B-.and offset portion B/ save Where the band D passes through V`said shield. The form of this shield A is, of course immaterial, but it is preierable'that it shouldfcorrespond in internal figurationto the pipe A to avoid unnecessary friction.

The band Dis made of any suitable material which will adapt itself, te the pulleys C C so that when said pulleys are driven the band will move freely with them. This band should have a suitable capillary attraction for the liquid fuel. I have found that a woven material furnishes good results.

The rush of air through the pipe Al comes in Contact with the liquid fuel carried by that part of the band D located in the path of movement of4 said air, and this fuel, being volatile, is readily taken up by the air and instantly becomes, in conjunction therewith, an explo- 4 sive mixture which is conveyed to the intended destination by a continuation of pipe A. It will be observedthat by the use of this form ofvapo1'izer,'the action of the engine is not choked or impeded. A supplemental damper (not shown) such as is commonly employed, may be placed vin the gas pipe Without in any Way affecting the action of the vaporizer itself While a uniform proportion of fuel to air, will be automatically maintained, as has already been indicated, this proportion may be varied by the manual adjustment of the presser roll E or other suitable means.

It may be understood that-the band may be porous or l screen-like so that air can easily pass throughl the same,

in which event the band may be made offany desired Width, since the' air can pass through the same as Well as The direction 'ofthe air through the intake pipe and vaporizer is immaterial; hence, either end of said pipe may be connected to the engine'. he direction kgf travel of the belt G and band. D isflikewise immaterial.

What l claim is:

1. In a"vaporizer, an air pipe, a fuel conveyor projecting into said pipe and in the path of movement ot' the air therethrough, 'means for moving said conveyer and varying the tension thereof, and meaus'for supplying fuel thereto. vv 2. In a vaporizer, an air pipe, a fuel conveyor-passing transversely through said pipe and in the pathl of travel of the air therethrough, means for moving said conveyor' and varying the tension thereof,.and means for supplying fuel thereto. y f

3. In a vaporzer, a pipe, an endless band fuel conveyer, supporting driving pulleys therefor on opposite sides of 'ipe'and externally thereof, said band conveyerpassing ,transversely through said p ipe and Athrough the path of movement of the air thereim'and means for supplying a liquid fuel to'said conveyer at a point externally of the pipe and means for varying. the volume of fuel carried hy said conveyer. l` p .a

4. In a vaporizer, a pipe, a fuel conveyer of woven material passing transverselyY` through said pip'e,`means for moving said fuel conveyer, and means for supplying a liquid fuel to said moving conveyer and means for varying the volume of fuel carried vby said conveyer.

' 5. in a vaporizer, a pipe, a movable fuel conveyl g belt extending in to the same and in the path of travel of the air therethrough, thel material of said conveyer having a capillary attractiveness'for liquid; means for supplying liquid -fnel to said conveyer, and means for manually lvarying.;- the amount of fuel carrying capacity of ,said conveyem by varying the tension thereof.` f l G. in a vaporizer, a pipe, a` well adjacent thereto forv holding liquid fuel, an endlessl band of flexible material projectingpinto said well, saidv band passing transversely through said pipe, and means at the other side of said pipe from said yvell for carrying said band at that side and .a tension regulating device *for said'band.

7. ln a vaporizer, a pipe, a well adjacent thereto for ,holding liquid fuel, a'n endless band'of flexible material projecting into said well, said hand passing transversely through saidpipe, means atthe other side of said pipev air therethrough, means for supplying fuel to said conveyer, and means vfor varying the amount of fuel' carried by said` conveyer by varyingthe tension thereof.

9. In a vaporizer, an air pipe, a fuel conveying band of porous or screen-like material passing into said pipe and in the` path of'movement of the air therethrough, means for moving said band, and means for supplyingr fuel t'here to and means for varying the tension of the hand.
